请问应该如何理解这段英语句子的结构，谢谢解答。Engineering graduates…？

Question

Engineering graduates were more likely to have started their job search.
尤其是were to have started·····，谢谢解答。

Answer 1

我是这么理解的：工程专业毕业生可能（早就）开始找寻工作了。
engineering graduate(s): 工程专业的毕业生
be more likely to do something... (更)可能做...
have done something.... 我觉得是完成时把，这个学过的时态忘记太多了。。。
所以你说的这个
were ... to have started ... 应该还是要连起来看不能拆开来看吧
were (过去式) more likely to have started (完成时) ，那把意思连起来看就是：更有可能已经开始
总体来看就是：更有可能早就已经开始寻找工作

Answer 2

原句：Engineering graduates were more likely to have started their job search already, and to have accepted a job. 工科毕业生更有可能已经开始找工作，并接受了一份工作。
结构：Engineering graduates（主语）were more likely to have started（谓语，亦称“复合谓语”） their job search（求职，找工作，固定短语，作宾语） already, and to have accepted（同前，只是省略了were more likely）a job（宾语）.本回答被网友采纳

Answer 3

工程专业的毕业生本来有可能开始他们的研究工作。were to have started(实际未做)
